All your work looks right so far. So now it looks like you have find times for the maximum and minimum of the speed, which will be a fairly straight-forward optimization problem.

Thanks a lot btw. So I'm guessing I should differentiate the expression again right? And from there work out the max and min turning points of the graph?

No, I think you're going the right way. The derivative does get a bit messy, but it helps that a and w are both constant, so you can throw those out. I think the answers you'll get will be fairly simple too.

Since I've now got sin^-1(0) I don't know where to proceed from there. As far as I know, that wouldn't yield a max/min value, or would it? And I don't know how the w in the argument factors into all this
